TC and CG Terminal Circuit: Description

DTC output mode is set by connecting terminals TC and CG of the DLC3.

The DTCs are displayed by blinking the SRS warning light.

HINT: 

• Make sure that DTCs which relate to the CAN communication system are not output. If any of these DTCs are output, check the CAN communication system. Refer to DIAGNOSIS SYSTEM [05/2013 - ] .
• When a warning light keeps blinking, a short to ground in the wiring of terminal TC of the DLC3 or an internal ground short in each ECU is suspected.
• The DTC output mode signal is transmitted through the CAN to each ECU including the center airbag sensor assembly. Thus if no systems enter DTC output mode, the ECM may have a malfunction.
